Making the case for the #CorsiRosenthalBox with studies.

A simple thread.
"no U.S. Energy Star certified air cleaners have CADR values (for either tobacco smoke, dust, or pollen) matching the CADR value for the CR Box even on low speed "

On cost? 1/10th.

1019 to 1444 m3/hr CADR.

(600 to 850 ft3/min)

Published here:
tandfonline.com/doi/full/10.10… ImageImage
An incredibly thorough study published in February 2023, with all of its authors from @NIOSH.

With universal masking in a 3-ply cotton mask, exposure to the relevant aerosol size is reduced by 88 to 94%, with the #CorsiRosenthalBox.

73% w/ CRBox alone.

sciencedirect.com/science/articl… ImageImage
Very good thread on this study here:

Essentially the same NIOSH team investigated HEPA efficacy.

65% reduction with HEPA alone.

So, at a much cheaper price, the #CorsiRosenthalBox gets better results.

cdc.gov/mmwr/volumes/7…
But can HEPAs remove SARS-COV-2 from the air? Yes.

(Would #CorsiRosenthalBox do the same? Yes - faster and cheaper.

Has it been studied specifically for this? No. HEPAs barely have.

Do the same laws of physics apply? Yes.)

journals.asm.org/doi/full/10.11… Image
But can HEPAs really remove SARS-COV-2 from the air?

Yes - in a UK hospital, HEPAs were off. Cov1d was in the air. Turned on. No more CoV1d.

1000 m3/hour CADR.

Remember the first study?

1019 to 1444 m3/ hour for the CR box.

@MarinaC_Dyb and her fellow authors found a massive reduction in aerosols in OCCUPIED classrooms using the #CorsiRosenthalBox. Also found that ALL of the air went in.

No wonder they have rolled them out to 400 locations.

Study is linked here:

Oh for Pete's sake. @elonmusk has just killed another thread.

Let me add these manually.
"Also found that ALL of the air went in" - quoting above to go into a little more detail:

This answers, in a study, the concern that it just moves the air around. That it won't go into the filter.

It does, and this had to be pointed out.
The CDC, of which NIOSH is part of, has officially recommended 5 ACH, minimum, and that DIY Air Cleaners are effective at reducing the risk of transmission of Cov1d.

The #CorsiRosenthalBox is
specifically mentioned as part of that solution.

cdc.gov/coronavirus/20… ImageImageImage
@3M has studied it in their formal lab - and is officially on board:

news.3m.com/2022-02-24-3M-…
The famous UL, Inc testing the safety of the #CorsiRosenthalBox, to make sure it won't catch on fire.

It won't - even if the filters are loaded up.

(The link that is out on Twitter appears to be dead.)

ul.org/library/2988
"Does Using Corsi–Rosenthal Boxes to Mitigate COVID-19 Transmission Also Reduce Indoor Air Concentrations of PFAS and Phthalates?"

Yes.

pubs.acs.org/doi/10.1021/ac… Image
Some have expressed surprise that this was found.

Dr. Corsi explains:

And the rest of your family?

30 case studies- oops, 30 of your stories here, where your family used the #CorsiRi
A thesis - a study, that found 7 PFAs, and exposure to for both dog and human. (@ShellyMBoulder collaborated).
elischolar.library.yale.edu/ysphtdl/2161/ Image
How do we know that dogs are affected? Because it is dogs that get experimented on.

And not to get too personal, but my dog has stage 4 chronic kidney disease. CKD can be caused by PFAs.

Did I do that? Or at least not prevent it? A lot of

wunc.org/health/2021-05… Image
years with no air filtration.

But hey - she is 15 years old, and it could be just old age.

In any event, I don't want to go into any more detail, but now I know better.

But besides PFAs, dogs can catch Cov1d.

As can cats.

In fact, from the study, we should see our cat as part of our family regarding virus transmission.

Can a cat or dog wear a mask?

Yes, with training.

But what if you could reduce their risk of catching Cov1d without all that? Image
And the risk to the rest of your family?

30 case studies- oops, 30 of your stories here, where your family used the #CorsiRosenthalBox as the centerpiece of your family pandemic prevention protocol.

And it worked.

Someone in the 7 Oaks School of Ontario IPC, like @zchagla, @DocDominik, @HotaSusy, @BogochIsaac @skepticalIDdoc has gone anonymous.

Remember - that group personally signed affidavits saying surgical masks are good enough to de-N95 nurses, who went on to die ....
At greater numbers than the population.

Who were sentenced to lives of LongCovid.

It all started in March of 2020, when the 7 Oaks School of Ontario IPC signed a nasty, but quiet, little petition to deny airborne precautions. Image
Then they signed those nasty little affidavits,with two fingers crossed I am presuming, in April of 2021.

Deliberately to demask the nurses. Image

Guess what?

In the next pandemic, these "RCT or STFU" worshippers plan on sacrificing you on the alter of RCTs.

This is Dr. Atle Fretheim 👇 talking about how they attempted to get masks randomized from his government.

And thankfully, shot down.
/+

Image
But they have figure out "this one weird trick!"

They are working on getting pre-approval from the WHO for what is called their "Master Protocols 👇," to then help smooth the way with their local government.

This is not an idle thing. Atle specifically used air filtration 👇@kprather88 @jljcolorado, as his example of a desired subject to give half of the class clean air in the beginning of a pandemic.

When we are MOST trying to stop the spread!

AVERAGE CO2 in the dead space below an N95? 1-3% - or 10,000 to 30,000 ppm. Scary?

No. You see that's the average.

Humans have focused on average or peak exhalations/waveforms.

We haven't studied the LOW POINT with capnography.

We have done it with simulations. Image
There are no published experimental (human) capnography studies inside N95 dead space that show the CO₂ dropping down as low as ~0.4% within a single exhalation. Human trials typically measure peak or average values rather than full breath waveforms.
As you can see, the amount of CO2 in the N95 goes down.

Why? Because the air around us has so much less CO2. When we inhale, it mixes with that high CO2.

Dilution and diffusion both at play.
journals.plos.org/plosone/articl…Image
As all of us who has ever worn a mask/N95, which is most of the world, knows, we don't suffer the effects of inhaling 30,000 ppm all day.

Lets look at this a different way.

What if we were in a room with huge CO2? That's what antimaskers are implying is going on.

How NOT to Science. A time travel thread and magic.

This is Helmut Traindl - the engineer who devised the procedure behind Walach CO2 study that was retracted after 16 days:
jamanetwork.com/journals/jamap…

Then, republished by Dr. Domingo just 6 months later.
sciencedirect.com/science/articl… Image
@RetractionWatch had an interesting write-up on how it was republished by Dr. Domingo.

It rings of plausible deniability. Except it smells vaguely of bad faith.

retractionwatch.com/2022/08/01/one…Image
Turns out that @TecnATox was founded, and is directed by Dr. Domingo.

You'll be hearing from me, Dr. Domingo - and a rather lot more people, once I get done writing all of this up.

You see, I found the pilot video.

So, in your apartment or hotel, we saw below how its heated facade, or front, could drive your downstairs neighbor cough into your lungs.

Let's step inside your living room now, and step forward in time to winter.

What happens if your sick neighbor is seated in that living /1
room?

Where is the worst place for them to be seated if you have your heat coming from a heat register up on the wall?

Next to your cold window.

The cold air cools your sick neighbor's exhaled infectious air, and drives it to the ground.

Where it sidles along until Image
Image
you and your family's bodies' thermal plumes pick up that air, and lifts it up to your faces to be breathed in.

Or....to put this in another way....if you go to a coffee shop as I like to do, and you see someone coughing next to a cold window? Do not dawdle.

Leave.
